Interest in multi-shaker vibration testing has increased significantly in the past few years. Multi-shaker testing has proven to be very useful for single-axis testing of test articles that are too large to be driven by a single shaker. Multi-shaker testing is also capable of more accurately simulating the actual multi-degree of freedom (MDOF) vibration environment experienced by your products. This course will provide an introduction to multi-shaker testing. It will cover multi-shaker test configurations, including multi-shaker/multi-axis and multi-shaker/single-axis configurations. The course will also cover the basics of multi-shaker vibration control, including measurement of MDOF vibration, selection of the proper number and location of control accelerometers, multi-shaker system identification, and multi-shaker control. Multi-shaker test environments covered will include random, sine, shock, and time waveform replication. The course will include demonstrations of both multi-shaker/single-axis and multi-shaker/multi-axis testing.
